B200761. (15 points) A chilt pulls a 25 kg sled containing a 3.0 kg dog along a straight path on a horizontal surface. He exerts a force of SN on the sled at an angle of 30° above the horizontal, as shown in the figure above. The coefficient of friction between the sled and the surface is 0.2 (a) On the dot below that represents the sled-dog system, draw and label a free-body diagram for the system as it is...
A father pulls a sled and child with a force of 220 N by a rope making an angle of 20 degree with the horizontal. If the sled and child has a mass of 47 kg, to the nearest hundredth of 3 m s what is the acceleration of the sled and child? Two crates of mass 75 kg and 110 kg arc in contact and rest on a rough horizontal surface. A 620 N force is exerted on the...
A child on a sled is initially at rest on an icy horizontal surface. The sled is pushed until it reaches a final velocity of 6.45 m/s in a distance of 10.8 m. The coefficient of friction between the ice and runners of the sled is 0.200, and the weight of the child and the sled is 345 N. Find the work done by the force pushing the sled. Find the minimum initial speed of a projectile in order for...
Could you please explain? Thank you!
kg15kg 20° B2007 A child pulls a 15 kg sled containing a 5.0 kg dog along a straight path on a horizontal surface. He exerts a force of 55 N on the sled at an angle of 20° above the horizontal, as shown in the figure above. Assume a constant friction force of 40N. (a) On the dot below that represents the sled-dog system, draw and label a free-body diagram for the system as...
A child applies a force F parallel to the z-axis to a 6.00 kg sled moving on the frozen surface of a small pond. As the child controls the speed of the sled, the 2-component of the force she applies varies with the 2-coordinate of the sled as shown in figure (Figure 1). Suppose the sled is initially at rest at x = 0. You can ignore friction between the sled and the surface of the pond. For related problemsolving tips...
You pull a your friend along in a sled (combined mass is 65 kg), by pulling the rope at an upward angle of 20 degrees with respect to the ground with enough force to keep the sled moving at a constant velocity of <3,0, 0> m/s. The coefficient of kinetic friction between the ground and the sled is 0.15. (a) Draw a force diagram for the friend/sled system. (b) Once you get to constant velocity, you pull the sled 15...
An Eskimo returning from a successful fishing trip pulls a sled loaded with salmon. The total mass of the sled and salmon is 50.0 kg, and the Eskimo exerts a force on the sled by pulling on the rope. The coefficient of kinetic friction between the sled and the ground is 0.200. (a) The Eskimo pulls the sled 6.00 m, exerting a force of 1.15 102 N at an angle of θ = 0°. Find the work done on the...
A dad pulls his child on a sled at a constant speed across a rugged snowy road with a force of 159 N in a direction of 42° above the horizontal. The mass of the child and sled is 38 kg. Compute the coefficient of friction. (HINT: Set up the force equations and Derive the expression the coefficient of friction between sled and snow.)
A 17-kg sled is being pulled along the horizontal snow-covered ground by a horizontal force of 22 N. Starting from rest, the sled attains a speed of 2.2 m/s in 8.3 m. Find the coefficient of kinetic friction between the runners of the sled and the snow.
A 19-kg sled is being pulled along the horizontal snow-covered ground by a horizontal force of 21 N. Starting from rest, the sled attains a speed of 1.9 m/s in 9.4 m. Find the coefficient of kinetic friction between the runners of the sled and the snow.
